I received this card the other day and was curious how it would perform in my Canon 5D Mark III, so I tested it against some of my other high speed cards. Obviously you are paying a premium for the write speed, so I wanted to make sure I got what I paid for, so to speak. Here’s what I came away with:

Camera Settings-Canon 5D Mark III with battery grip – 2 fully charged batteries (grip doesn’t matter)-Freshly in-camera formatted CF cards-ISO 100, 1/8000s, body cap (so f/0, manual focus)-ALO, High ISO NR, vignette removal, CA correction OFF-RAW-High Speed DriveNote: I realize that the body cap photos are all black and real photos will be larger and slow the camera more, but I think that this is the only way to have a 100% reproducible test.

Test-Depress shutter fully until the camera slows-Wait for buffer write to finish-Press image review – look at # of images, subtracting the extra frame that indicated the buffer was full

The new card isn’t quite a 50% boost over the previous generation, but it’s close, and being able shoot at 6fp for at least 5 seconds straight in a 5DIII is excellent. I’m sure the 1DX, D4, and other cameras would also benefit from the card.

The card works fine. Prices vary a lot at different major retailers. Make sure your reader is new or firmware-updated to UDMA7, at which point the download speed is amazing. If the speed is the same as or slightly slower than older cards, that’s how you’ll know you need UDMA7 update or a new reader.

I wanted to wait a bit before I reviewed this card, because I was skeptical that it would be much of an improvement over the less expensive cards I’ve purchased before from Sandisk. My previous best card was 90MB/s and the difference was very noticeable. The biggest difference is when the card is getting to the half full mark, or when you’re shooting video over 30 seconds. It’s worth the extra cost if you are planning to use this card as your go-to for shooting video, shooting big events in still and video, or you want to bring only one card on a long vacation.
